Claude More powerful new models consume allowances faster: for the same 200 USD, Opus delivers 15000 USD, while Fable delivers only 3000 USD BlockBeats news:AI prominent developer and T3 Code founder Theo found that Anthropic's newly released Fable 5.2 is more powerful, but subscribers receive substantially less API-equivalent usage.
Theo has long tracked actual request data for Claude Code. By his estimate, for the same monthly 200 USD Claude Ultra subscription fee, using Opus 5.5 provides approximately 15000 USD worth of API usage per month; switching to Fable 5.2 yields only about 3000 USD, a difference of nearly 5 times.
Anthropic also limits Ultra users to spending at most 50%of their total weekly allowance on Fable. Even if they have not exhausted their total allowance, they must switch to another model or pay extra to continue once they reach the Fable limit.
Theo further estimated the actual workload: if Opus was used exclusively for 1 weeks, 5.5 approximately 1200 interaction rounds and 230 task sessions could be completed. If the Fable allowance were exhausted first and then the user switched to Opus, the total number of interaction rounds would fall to approximately 900, although the number of completed task sessions might be slightly higher. That is because Fable can sometimes complete a task in a single attempt without repeated exchanges.
Fable 5.2's API unit price is actually 20%lower than the previous generation's, with input and output Token priced at 8 USD and 40 USD per million, respectively, but it is still twice the price of Opus 5.5. Anthropic also explicitly warns that Fable consumes subscription allowances faster than other Claude models.
Anthropic is currently giving eligible subscribers 1 to 3 Fable allowance resets, depending on the length of their subscription. Each reset restores the Fable allowance already used that week, allowing users to continue without waiting until the following week.
